Great Southern BioBlitz | 28-31 Oct 2022

Great Southern BioBlitz 2022

The ‘Great Southern BioBlitz’, or ‘GSB’ for short, is an international period of intense biological surveying in an attempt to record all the living species within several designated areas across the Southern Hemisphere in Spring.

​The purpose of this event is to highlight both the immense biodiversity spread across the Southern Hemisphere in the flourishing springtime, as well as to engage the public in science and nature learning using the citizen science platform iNaturalist. In Spanish they are known as ‘Gran Biobúsqueda del Sur’, while in Portuguese they are known as ‘Grande BioBlitz do Hemisfério Sul’.

​By the end of October, the natural world is on full throttle. Flowers are blooming, insects are emerging, birds are singing, and reptiles are coming out of their winter hibernation. It makes sense for the Southern Hemisphere to observe life at this time of year. 

How to get involved?

To contribute to the event, all you need to do is download the iNaturalist application to your handheld device or make an account on your computer and make an observation(s) between 28 – 31 October 2022.

​After this date, you will have 14 days to upload and identify your observations (until 14th November 2022).

Don’t worry if you cant identify the organism. Just make sure you get some good clear photos or sounds.


Where can you participate?

First and foremost, all observations must be made somewhere in the southern hemisphere during the event.​

The platform has several nodes that upload the collected data to a national database. With that in mind, it’s best to use your local ‘Node’ (see below) if there is no node in your area then use
